I've been trying to solo the F & I quest for the catalysts for weeks. Initially to learn the fastest way through the jumping puzzle and to memorize all the encounters and their mechanics. On the final boss, I still struggle hitting the WHITE targets because of their location UNDER the map. I'm learning the spots that make that easier. What's driving me CRAZY, particularly in a TIMED EVENT, is RESPAWNING OUTSIDE THE PORTAL!!! It forces me to waste so much time just getting back to the boss arena, especially when I'm down to a minute and I'm so close to finishing. Then there's having the dark and light orbs spawning and falling off the map. That's a good one too. Bungie, PLEASE. FIX THIS!!! or I GIVE UP.
